BACKGROUND

CC chemokine receptor 3 (CCR3) is a seven-transmembrane Gprotein-coupled receptor, which binds to a variety of C—C chemokines,including eotaxin (CCL11), eotaxin-3 (CCL26), MCP-3 (CCL7), MCP-4(CCL13), and RANTES (CCL5). CCR3 is known to be a major chemokinereceptor expressed on allergic inflammatory cells, includingeosinophils, basophils, mast cells, and T helper 2-type CD4⁺ cells(Combadiere et al., J. Biol. Chem. 1995, 270, 16491-16494; Post et al.,J. Immunol. 1995, 155, 5299-5305). Eosinophils have been implicated inthe pathogenesis of a number of allergic diseases, such as bronchialasthma (Durham and Kay, Clin. Allergy 1985, 15, 411-418; Kroegel et al.,J. Allergy Clin. Immunol. 1994, 93, 725-734), allergic rhinitis (Durham,Clin. Exp. Allergy 1998, 28 Suppl. 2, 11-16.), atopic dermatitis (Leung,J. Allergy Clin. Immunol. 1999, 104, S99-108), and eosinophilicgastroenteritis (Bischoff et al., Am. J. Gastro. 1999, 94, 3521-3529).It has been demonstrated that activated eosinophils release major basicprotein (MBP), which blocks inhibitory M2 muscarinic receptors (M2Rs) onnerves, increasing acetylcholine release, and potentiating vagallymediated bronchoconstriction (Evans et al., J. Clin. Invest. 1997, 100,2254-2262).

Numerous reports indicate that CCR3 plays important roles in allergicconditions. For example, it has been reported that, in both atopic andnonatopic asthma patients, there are increases in both mRNA and proteinlevels of CCR3 and its ligands, eotaxin, eotaxin-2, RANTES, and MCP-4(Ying et al., J. Immunol. 1999, 99, 6321-6329). It has also beendemonstrated that CCR3 gene deletion impairs eosinophil recruitment inan acute model of experimental asthma (Humbles et al., Proc. Natl. Acad.Sci. USA 2002, 99, 1479-1484; Ma et al., J. Clin. Invest. 2002, 109,621-628; Pope et al., J. Immunol. 2005, 175, 5341-5350; Fulkerson etal., Proc. Natl. Acad. Sci. USA 2006, 103, 16418-16423). Furthermore,studies have shown that CCR3 antagonists, such as anti-CCR3 monoclonalantibodies, block binding of CCR3-ligands to either CCR3 transfectantsor eosinophils, thus blocking chemotaxis of eosinophils induced by C—Cchemokines, such as eotaxin, RANTES, or MCP-3 (Heath et al., J. Clin.Invest. 1997, 99, 178-184; Grimaldi et al., J. Leukocyte Biol. 1999, 65,846-853; Justice et al., Am. J. Physiol. 2003, 284, L168-L178).Therefore, CCR3 antagonists are potentially useful for the treatment ofinflammatory diseases, such as allergic rhinitis and allergic asthma. Inaddition, CCR3 antagonists are also potentially useful blockinginfection of CCR3 expressing cells by some microorganisms, such as HIV,as CCR3 is known to be an entry co-receptor for some microorganisms.

The term “CCR3” refers to CC chemokine receptor 3 or a variant thereof,which is capable of mediating a cellular response to a variety ofchemokines, including, but not limited to, eotaxin (CCL11), eotaxin-3(CCL26), MCP-3 (CCL7), MCP-4 (CCL13), and RANTES (CCL5). CCR3 variantsinclude proteins substantially homologous to a native CCR3, i.e.,proteins having one or more naturally or non-naturally occurring aminoacid deletions, insertions or substitutions (e.g., CCR3 derivatives,homologs and fragments), as compared to the amino acid sequence of anative CCR3. The amino acid sequence of a CCR3 variant is at least about80% identical, at least about 90% identical, or at least about 95%identical to a native CCR3.

The term “CCR3 antagonist” refers to a compound that, e.g., partially ortotally blocks, decreases, prevents, inhibits, or downregulates CCR3activity. The term “CCR3 antagonist” also refers to a compound thatbinds to, delays the activation of, inactivates, or desensitizes a CCR3receptor. A CCR3 antagonist may act by interfering with the interactionof a CCR3 receptor and its chemokine ligand, including, but not limitedto, eotaxin (CCL11), eotaxin-3 (CCL26), MCP-3 (CCL7), MCP-4 (CCL13),and/or RANTES (CCL5).

The terms “CCR3-mediated disorder or disease” and “a condition, disorderor disease mediated by CCR3” refer to a condition, disorder, or diseasecharacterized by inappropriate, e.g., less than or greater than normal,CCR3 activity. Inappropriate CCR3 functional activity might arise as theresult of CCR3 expression in cells which normally do not express CCR3,increased CCR3 expression or degree of intracellular activation, leadingto, e.g., inflammatory and immune-related disorders or diseases; ordecreased CCR3 expression. A CCR3-mediated condition, disorder ordisease may be completely or partially mediated by inappropriate CCR3activity. In particular, a CCR3-mediated condition, disorder or diseaseis one in which modulation of a CCR3 receptor results in some effect onthe underlying condition or disorder, e.g., a CCR3 antagonist or agonistresults in some improvement in at least some of patients being treated.

Wherethe compound provided herein contains an alkenyl or alkenylene group,the compound may exist as one or mixture of geometric cis/trans (or Z/E)isomers. Where structural isomers are interconvertible via a low energybarrier, the compound may exist as a single tautomer or a mixture oftautomers. This can take the form of proton tautomerism in the compoundthat contains, for example, an imino, keto, or oxime group; or so-calledvalence tautomerism in the compound that contain an aromatic moiety. Itfollows that a single compound may exhibit more than one type ofisomerism.

The compounds provided herein may be enantiomerically pure, such as asingle enantiomer or a single diastereomer, or be stereoisomericmixtures, such as a mixture of enantiomers, e.g., a racemic mixture oftwo enantiomers; or a mixture of two or more diastereomers.

Methods of Synthesis

The compounds provided herein can be prepared, isolated, or obtained byany method known to one of skill in the art. For an example, a compoundof Formula Ia or Formula I can be prepared by a synthetic scheme asillustrated in Scheme 1. In the first step, a nitrobenzene reacts with a1,3,5-trisubstituted benzene in the presence of base (such as potassiumcarbonate or sodium hydride) via an aromatic substitution reaction. Theproduct nitroaryl is reduced with a reducing agent (such as TiCl₂ orsodium hydrosulfite) to an aniline, which is then converted to asulfonyl chloride via a Sandmeyer reaction. A compound of Formula Ia orFormula I is formed by reacting the sulfonyl chloride with anappropriate nitrogen-containing heterocycle in the presence of a base,such as triethylamine.

A compound of Formula II can be prepared by a synthetic scheme analogousto that illustrated in Scheme 1.

A compound of Formula Ia or Formula I can also be prepared by thesynthetic scheme illustrated in Scheme 2. In the first step, an anilineis first converted to a sulfonyl chloride via a Sandmeyer reaction.Subsequently, the sulfonyl chloride is reacted with an appropriatenitrogen-containing heterocycle in the presence of a base, such astriethylamine, to form a 2-chloro-5-substituted sulfonamide, which isthen reacted with an appropriate 1,3,5-trisubstituted benzene byaromatic substitution reaction in the presence of a base, such aspotassium carbonate or sodium hydride, to form a compound of Formula Iaor Formula I.

A compound of Formula II can be prepared by a synthetic scheme analogousto that illustrated in Scheme 2.

One class of osmotic agents water-swellable hydrophilicpolymers, which are also referred to as “osmopolymers” and “hydrogels,”including, but not limited to, hydrophilic vinyl and acrylic polymers,polysaccharides such as calcium alginate, polyethylene oxide (PEO),polyethylene glycol (PEG), polypropylene glycol (PPG),poly(2-hydroxyethyl methacrylate), poly(acrylic) acid, poly(methacrylic)acid, polyvinylpyrrolidone (PVP), crosslinked PVP, polyvinyl alcohol(PVA), PVA/PVP copolymers, PVA/PVP copolymers with hydrophobic monomerssuch as methyl methacrylate and vinyl acetate, hydrophilic polyurethanescontaining large PEO blocks, sodium croscarmellose, carrageenan,hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC),hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) andcarboxyethyl, cellulose (CEC), sodium alginate, polycarbophil, gelatin,xanthan gum, and sodium starch glycolate.

The other class of osmotic agents is osmogens, which are capable ofimbibing water to affect an osmotic pressure gradient across the barrierof the surrounding coating. Suitable osmogens include, but are notlimited to, inorganic salts, such as magnesium sulfate, magnesiumchloride, calcium chloride, sodium chloride, lithium chloride, potassiumsulfate, potassium phosphates, sodium carbonate, sodium sulfite, lithiumsulfate, potassium chloride, and sodium sulfate; sugars, such asdextrose, fructose, glucose, inositol, lactose, maltose, mannitol,raffinose, sorbitol, sucrose, trehalose, and xylitol,; organic acids,such as ascorbic acid, benzoic acid, fumaric acid, citric acid, maleicacid, sebacic acid, sorbic acid, adipic acid, edetic acid, glutamicacid, p-toluenesulfonic acid, succinic acid, and tartaric acid; urea;and mixtures thereof.

Osmotic agents of different dissolution rates can be employed toinfluence how rapidly the active ingredient(s) is initially deliveredfrom the dosage form. For example, amorphous sugars, such as MANNOGEM™EZ (SPI Pharma, Lewes, Del.) can be used to provide faster deliveryduring the first couple of hours to promptly produce the desiredtherapeutic effect, and gradually and continually release of theremaining amount to maintain the desired level of therapeutic orprophylactic effect over an extended period of time. In this case, theactive ingredient(s) is released at such a rate to replace the amount ofthe active ingredient metabolized and excreted.

The core can also include a wide variety of other excipients andcarriers as described herein to enhance the performance of the dosageform or to promote stability or processing.

Materials useful in forming the semipermeable membrane include variousgrades of acrylics, vinyls, ethers, polyamides, polyesters, andcellulosic derivatives that are water-permeable and water-insoluble atphysiologically relevant pHs, or are susceptible to being renderedwater-insoluble by chemical alteration, such as crosslinking Examples ofsuitable polymers useful in forming the coating, include plasticized,unplasticized, and reinforced cellulose acetate (CA), cellulosediacetate, cellulose triacetate, CA propionate, cellulose nitrate,cellulose acetate butyrate (CAB), CA ethyl carbamate, CAP, CA methylcarbamate, CA succinate, cellulose acetate trimellitate (CAT), CAdimethylaminoacetate, CA ethyl carbonate, CA chloroacetate, CA ethyloxalate, CA methyl sulfonate, CA butyl sulfonate, CA p-toluenesulfonate, agar acetate, amylose triacetate, beta glucan acetate, betaglucan triacetate, acetaldehyde dimethyl acetate, triacetate of locustbean gum, hydroxylated ethylene-vinylacetate, EC, PEG, PPG, PEG/PPGcopolymers, PVP, HEC, HPC, CMC, CMEC, HPMC, HPMCP, HPMCAS, HPMCAT,poly(acrylic) acids and esters and poly-(methacrylic) acids and estersand copolymers thereof, starch, dextran, dextrin, chitosan, collagen,gelatin, polyalkenes, polyethers, polysulfones, polyethersulfones,polystyrenes, polyvinyl halides, polyvinyl esters and ethers, naturalwaxes, and synthetic waxes.

Semipermeable membrane can also be a hydrophobic microporous membrane,wherein the pores are substantially filled with a gas and are not wettedby the aqueous medium but are permeable to water vapor, as disclosed inU.S. Pat. No. 5,798,119. Such hydrophobic but water-vapor permeablemembrane are typically composed of hydrophobic polymers such aspolyalkenes, polyethylene, polypropylene, polytetrafluoroethylene,polyacrylic acid derivatives, polyethers, polysulfones,polyethersulfones, polystyrenes, polyvinyl halides, polyvinylidenefluoride, polyvinyl esters and ethers, natural waxes, and syntheticwaxes.

The delivery port(s) on the semipermeable membrane can be formedpost-coating by mechanical or laser drilling. Delivery port(s) can alsobe formed in situ by erosion of a plug of water-soluble material or byrupture of a thinner portion of the membrane over an indentation in thecore. In addition, delivery ports can be formed during coating process,as in the case of asymmetric membrane coatings of the type disclosed inU.S. Pat. Nos. 5,612,059 and 5,698,220.

The total amount of the active ingredient(s) released and the releaserate can substantially by modulated via the thickness and porosity ofthe semipermeable membrane, the composition of the core, and the number,size, and position of the delivery ports.

The pharmaceutical compositions in an osmotic controlled-release dosageform can further comprise additional conventional excipients or carriersas described herein to promote performance or processing of theformulation.

The cell suspension was thentransferred to a filtration plate (#MAFB, Millipore), and washed 3 timeswith the binding buffer containing 0.5 M NaCl, scintillant added, andthe radioactivity was counted on a TopCount (Packard). For thedetermination of non-specific binding, the cell suspension and[¹²⁵I]-labeled human eotaxin/CCL11 were incubated in the presence of 500nM of unlabeled human eotaxin/CCL11.
